Boosting Energy Storage Performance of Lead‐Free Ceramics via Layered Structure Optimization Strategy

“…During the development of new energy sources, energy conservation and environmental protection as well as development and exploration of efficient energy storage and conversion systems are also crucial. [ 1–4 ] Among the various existing energy storage devices, dielectric capacitors exhibit excellent voltage endurance and high power density, which make them suitable for application in pulsed power systems and electronic devices. [ 5–8 ] Nevertheless, the energy density of dielectric capacitors is significantly lower than that of batteries and other energy storage devices, which limits the application of dielectric capacitors in energy storage fields.…”

“…During the development of new energy sources, energy conservation and environmental protection as well as development and exploration of efficient energy storage and conversion systems are also crucial. [1][2][3][4] Among the various existing energy storage devices, dielectric capacitors exhibit excellent voltage endurance Toward the development of lead-free AFE ceramics, Zhao et al [9] enhanced the antiferroelectricity of AgNbO 3 (AN) with Ta 5+ modified, which resulted in an enhanced energy storage performance (W rec = 4.2 J cm −3 , and η = 69%). Subsequently, Yan et al [26] codoped AgNbO 3 with Bi 3+ and Zn 2+ and further enhanced W rec to 4.6 J cm −3 ; however, the corresponding η was only 57.5%.…”

Superior energy storage properties in NaNbO3-based ceramics via synergistically optimizing domain and band structures

“…30 The Raman peaks decrease in intensity and broaden in shape when x increases from 0 to 15, suggesting enhanced local structure heterogeneity or a relaxor feature with the increasing Ta content. 37,41 Fig. 2(g) shows the temperature dependent Raman spectra of the representative NBNT10 ceramics from −110 °C to 220 °C, where no obvious peak shifts are observed, manifesting the diffusive phase transition of the NBNT10 ceramics.…”

Molecular Dynamics Simulation on the Wettability of Nanoscale Wrinkles: High Water Adhesion of Rose Petals

“…Bioinspired surfaces with microscale or nanoscale structures have widespread applications because of their unique properties, for example, self-cleaning, , energy harvesting, − thermal management, , radiative cooling, , drag reduction, , and reversible adhesion . The droplets deposited on the lotus leaf or rose petal both exhibit a high contact angle (>150°).…”
